“Most of the young people entering professional, technical, and managerial occupations start their occupational training in a school. Higher education is predominantly occupational education and is becoming more 80 each year. In 1980-81, only 17 percent of rnaster9s degrees and 33 percent of bachelor's degrees were in traditional liberal arts fields. Many of those who get these degrees remain in school to get a Ph.D., M.D., D.D.S. or L.L.B., all of which certify three or more years of intensive occupational training. Consequently, almost all college graduates obtain training for a particular occupation before leaving school.”
